Three capacitors $C_1$, $C_2$, and $C_3$, whose values are $10$ $\mu F$, $5$ $\mu F$, and $2$ $\mu F$ respectively, have
breakdown voltages of $10V$, $5V$, and $12V$ respectively. For the interconnection shown, the maximum
safe voltage in Volts that can be applied across the combination and the corresponding total charge
in $\mu C$ stored in the effective capacitance across the terminals are respectively

1. $2.8$and $36$
2. $7$ and $19$
3. $2.84$ and $324 4.$7$and$80\$
